About the IABPA


Welcome to the official website of the IABPA


The purpose of this page is to introduce you to the IABPA and inform you about our association.  This website serves as a vehicle for providing information and resource material to assist our membership and the BPA community in their quest for education, professional development and networking.  This website also serves to encourage and cultivate productive relationships among our membership and the BPA community and, most importantly, to support the pursuit of our organizational objectives.  

Our website will continue grow as new information and resource material is added.



Who we are, and what we do......

The International Association of Bloodstain Pattern Analysts is an organization of forensic experts specializing in the science of bloodstain pattern analysis.  The IABPA is currently comprised of approximately 600 members, worldwide, from various scientific, law enforcement, criminal justice and academic backgrounds.



Violent crimes often result in bloodshed.  When liquid blood is acted upon by physical forces, bloodstains and bloodstain patterns may be deposited on various surfaces, including the clothing of the individuals present at the crime scene.  When bloodstain evidence is examined by a qualified analyst, valuable information can be developed concerning the events which lead to their creation.  This information can then be used to assist in the reconstruction of the incident or crime, and, can assist in the evaluation of statements from the witnesses and/or the crime participants. 

The analysis of bloodstain evidence has become a valuable instrument in the successful prosecution and exoneration of those charged with violent crimes.  In recent years, it has also assisted in overturning many wrongful convictions.  The analysis of bloodstain evidence has also been utilized to assist in the reconstruction of incidents having occurred centuries ago that had previously remained a mystery.   

The science of BPA continues to evolve and improve, as new research data and technology become available.
